J OIN'J. CONNECTION.

To all whom it may concern:

lie it known that I, SILAS C. MAODOWNEY, a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented a new and useful construct the bars, so that the inner and outer bars may be secured in position in the frame of the window entirely from the outside, and in such a manner, as to not entail but a very little labor and trouble.

Another object of the invention is the utilization of wood screws or machined screws, arranged angularly through the bars so as to draw them closely together, and to insure the lock joint more secure.

Afurther ob ect of the invention is the provision of buffer blocks with which the glass contacts. These buffer blocks in the present instance are to be constructed of wood orlike material, so as to preserve the condition of the glass.

In the drawings, there is disclosed certain features of the present invention, but in practical fields these features may necessitate alterations, to which the applicant is entitled provided the alterations are comprehen ed within the .scope of what is claimed.

The invention comprlses further features and combination of parts, as hereinafter d1sclosed, shown in the drawings and claimed.

In the drawings :Figure 1 is a sectional view, through a window frame having sheet metal facing plates conforming to the shape of the frame, and showing the sash or plate glass bars secured in position with relation to the glass. F i 2 is a view in perspective, showing a modified form of sheet metal facing plate. Fig. 3 is a sectional view similar to Fig. 1, showing a modified form of sheet 'metal facing plate, and a modified form of buffers for the plate glass. Fig. 4 is a detail sectional view, showing the application of the,

bars to a stone sill, between which and the bars a wood facing is arranged. Fig. 5 is a sectional perspectlve viewshowing the application of the bars directly to a stone sill, the inner bar being anchored to the wood flooring or facing, with an L-shaped buffer block arranged between the bars, whereby the outer bar may be secured to it by machine screws, whereby the two bars may be brought securely together against the glass. Fig. 6 is a view in perspective and partly in section also showing the application of the bars, but as applied to a $111 entirely wood. Fig. 7 is a sectlonal view through a portion of a show window, showing a part of the plate glass and the means for holding it in position, and illustrating the base of the panel 6.

Referring more particularly to the drawings, 1 throughout Figs, 1, 2 and 3 designates the main strips of the window frame, while 2 denotes supplemental strips. Arranged adjacent the main strips are sheet metal facing bars 3, which in Figs. 1, 2 and 3 vary in shape and design. The sheet metal facing bars are angular as shown at 4 so as to fit the supplemental strips. In Fig. 2 the facing bar, as shown at 5 is constructed in the form of a step beading. In Fig. 1 a portion of a panel 6 having a sheet metalfacing 7, silrrounded by a sheet metal molding or heading 8, is shown. The molding or beading 8 is secured in position by an angular disposed screw 9.

The sash or plate glass holding bars are arranged adjacent the sheet metal facing bars. The inner sash or glass holding bar 10 is first secured in position by the screws 11, as shown in the drawings. The sash or glass bars 10 are provided with flanges 12,

which are engaged by the hooked flanges 13 of the outer sash or glass holding bars 14, thus constituting a lock joint. The free portions 15 of the mner' and outer sash of the glass. holding bars, are spaced apart, as shown, for the reception of the plate glass 16. By virtue of the screws 17 the outer Patented oer. raters.

bars are secured in position, the said screws 17 acting as means for drawing the inner and outer bars closely together and against the glass.

In Figs. 1, 2 and 6 the screws 17 not only secure the bars 10 and 14 in position but also anchor the buffer blocks 18 in position. The

buffer blocks are. constructed of wood or like material, and are mounted in the sheet metal trough members The buffer blocks are designed to be contacted with by the edges of. the plate glass, in order to insure the glass against cracking and chipping. The screws 17 penetrate the bufier blocks angularly as shown. By arranging the screws angularly the bars .10 and 14 are drawn together. K

' In Figs. 3, 4 and 5 L-shaped buffer blocks 20 are utilized, and the sheet metal trough shape holders 19 are dispensed with. The L-shaped buffer blocks 20, in Figs. 3, 4 and 5 are first secured in position by the screws 11 (which anchor the inner bars 10 in position). The lock joints of the bars 10 and 14 and the shoulder portions 21 are engaged by the beveled portions 22 of the l.-

shaped buffer blocks, thus constituting means for further holding the blocks in position. In Figs. 4 and 5 one of the'bevels 22 is dispensed with, as shown at 23. On the sides and the top of the window frame the buffer blocks may be dispensed with if so desired, but in every instance, the buffer blocks are entirely essential at the base of the plate glass, in order to support the lower edge of the glass from contact with the inner bar 10, especially when stone sills 24 are employed, as shown in Fig. 5. When stone sills are used the wood screws 17 are dispensed with, and in their stead machine screws 25 are utilized, which only penetrate the L-- shaped buffer blocks.

The inner and outer sash or glass holding bars throughout every figure of the drawings are provided with vent openings 26, which are formed in the lock joint of the bars, so as to permit of ventilation between the bars. However, these vent openings 26 are only disclosed in Figs. 5 and 6.

In Fig. 4 a stone sill 27 is illustrated, over which is extended a wood facifig or a portion of the flooring 28, which is covered by a metallic facing 29, against which the bars 10 and 14 are arranged, the screw 17 penetrates the wood 28 angularly, as in the other structures.

From the foregoin it is apparent that there has been devise a simple, novel, and inexpensive structure and arrangement of ,sash holding bars having a novel form of lock joint between them, and through. which a single'row of screws penetrate from the outside, so as to draw the bars together closely Furthermore this unique structure has been found to be practicable, in the construction of show windows and the like. The buffer blocks (which are constructed of wood or like material) have been found to.

beundoubtedly practicable, because they do not become. out or worn by the glass, as do rubber or similar material.

The buffer blocks 18 and 20 may be made e whatsoever, and constructed of any suitable material, whether metal, wood or any other suitable fiber or metal.

If the L-shaped bufier block 20 is conthe bars closely against side of the glass, and another structed' of cast brass or other suitable metal, the same is threaded for any size machine screw, as shown at 25 in Fig. 5, for the reason that this screw holds the member 15 against the plate glass, glass in position securely, thus preventing the glass from being blown out. However, the buffer block 20 is only made of metal, instead of wood, where there is no wood sill jamb or sash head That is, the metal buffer block is used onra stone,,iron or marble sill or the like. The buffer; blocks, whether l.-

.shaped or otherwise shaped, may or may not be used on the sides or head of the window frame, and if used on the sides or.head of the show window frame, the screw 17, shown in Fig. 1 is used for holding the same in place.

In Fig. 7 of the drawings the base of the panel 6 is illustratedfin which the facing 7 overlaps an extension 9 of the strip 9*, in order to prevent rain or other foreign matter from running behind the strip 9 thus preventing the -'wood panel 6 from becoming rotted. The lower portion of the molding so as to hold the or beading 8 as shown at a, coversthe latter facing 7 and the extension 9. The strip 9* may be stepped or otherwise shaped as shown at 70, and the lower flange h of the strip 9* turns under the base on of the panel.

The invention having been set forth, what is claimed as new and useful is 1. In combination, a window frame, sash or glass holding bars provided, with interlocking joint flanges, the bars adapted to be arranged one on each side of a glass, a single row of screws penetrating the bars from the outside of the glass for drawing the glass and insuring a tight fiange'jdint, and wood buffer blocks and sheet metal holders therefor penetrated by the screws, arranged to be contacted with by the glass.
